Wohler VMQ-2D 4-Channel AES Audio Monitor
This unit permits simultaneous monitoring of up to four audio sources on two AES inputs with "voice quality" fidelity. Because each channel has its own dedicated power amplifier and speaker, the audio sources remain completely separate from analog input to output. When listening within "Ultra Near Field" distances of 1 to 3 feet, these discrete speaker outputs provide enhanced source distinction when compared to designs with four inputs mixed into a single output.
Each channel has its own volume control, plus mute button with LED mute indicator and a "signal active" LED, allowing the operator to determine, at a glance, which channels are muted or active.
A stereo headphone jack has channels 1 and 2 summed on the left side, and channels 3 and 4 on the right side.
The unit is fully magnetically shielded to allow operation immediately adjacent to all CRT video monitors. Its light weight and shallow-depth chassis make it ideal for use in portable and mobile vehicle applications.
